The Talented Husband (The Saint TV Series)

Plot
Madge, a friend of The Saint, has recently married John Clarron, an ex-actor and unsuccessful playwright and is now an invalid following an accident in which a heavy pot fell on her. Simon goes to visit her at her home in Cookham on the river Thames and meets Adrienne Halberd. She is an insurance investigator, very interested in Clarron since his first two wives, both heavily insured, died in suspicious circumstances. The Clarrons employ an old Irish house-keeper, Mrs. Jafferty, but when Clarron is away in London Simon and Adrienne search the house and the lady is nowhere to be found.

Origin
This episode was adapted from a story of the same name from the 1956 book The Saint Around the World.
